Depends. : Barrett's esophagus is a condition that arises due to chronic acid reflux or gerd. It increases the likelihood of developing esophageal cancer. There is a procedure called halo which can cure barrett's without major surgery. The more important step is to get his reflux fixed by either a tif (transoral incisionless fundoplication) or a laparoscopic nissen fundoplication.
